[0025] This specific embodiment is a furniture wood drilling machine with adjustable hole spacing, and its structural diagram is shown as follows: Figures 1-6 As shown, it includes a moving platform 1 and a guide rail 2. The moving platform 1 is slidably connected to the guide rail 2. The top surface of the moving platform 1 is fixedly connected to a bracket 3, and the top surface of the bracket 3 is fixedly connected to a placement plate 4. A driving box is provided on the upper side of the placement plate 4, and a pressure plate 5 is provided on the lower side of the driving box. The side walls of the placement plate 4 are fixedly connected to a first cylinder 6 near both ends, and the output end of the first cylinder 6 is fixedly connected to the pressure plate 5. A number of support plates 13 are fixedly connected to the bottom surface of the drive box, and a support plate 7 is fixedly connected to the rear side wall of the bracket 3. The top surface of the support plate 7 is slidably connected to a transmission box 8. The top surface of the transmission box 8 is equipped with a cover plate 28. The provision of the cover plate 28 facilitates the later inspection and maintenance of the sheave 15 and the belt 16. A transmission assembly is provided in the inner cavity of the transmission box 8, and a docking assembly is provided on the side of the transmission box 8 close to the placement plate 4, and a pushing assembly is provided on the top surface of the support plate 7.

[0026] like Figure 4 and Figure 5 As shown, the transmission assembly includes several rotating shafts 14 rotatably connected to the inner wall of the transmission box 8, the rear end of the rotating shaft 14 extends to the outside of the transmission box 8, and the side walls of the rotating shaft 14 are fixedly connected to two groove wheels 15. The groove wheels 15 are connected with belts 16 for transmission, and the belts 16 are staggered. The side walls of the transmission box 8 are fixedly connected to the motor 9, and the output end of the motor 9 is fixedly connected to one of the rotating shafts 14.

[0027] Among them, by setting up a transmission component, when the motor 9 is running, the transmission between the groove wheel 15 and the belt 16 can make multiple drill bits rotate synchronously in the same direction, which is convenient for drilling holes in wood. This transmission structure has the characteristics of simple structure, high transmission efficiency and low maintenance cost.

[0028] like Figure 5 and Figure 6As shown, the docking assembly includes a mounting cylinder 17 assembled on the rear end of the rotating shaft 14, and a swivel 18 is threadedly connected to the side wall of the mounting cylinder 17. The side wall of the swivel 18 is inclined. A plurality of cavities 19 are opened inside the mounting cylinder 17, and a push rod 20 is movably connected in the cavity 19. Both ends of the push rod 20 pass through the mounting cylinder 17, and a rebound part is provided on the side wall of the push rod 20. The side wall of the swivel 18 is fixedly connected to a hexagonal ring 24.

[0029] Among them, after the drill bit is fixed using the docking assembly, the hexagonal ring 24 can be rotated with a wrench to further improve the stability of the drill bit; in addition, the inner wall shape of the mounting tube 17 can be circular, quadrilateral, hexagonal or other shapes, which are limited according to the cross-sectional shape of the drill bit. A limiting hole or a long hole can be pre-opened on the side wall of the drill bit to facilitate the insertion of the push rod 20 for fixation.

[0030] like Figure 6 As shown, the resilient member includes a circular plate 21 fixedly connected to the side wall of the push rod 20. A spring 22 is sleeved on the side wall of the push rod 20 between the circular plate 21 and the side wall of the cavity 19. By providing the resilient member, when the drill bit needs to be removed, only the swivel 18 needs to be reversed, and the push rod 20 uses the force of the spring 22 to return to contact with the drill bit, thus avoiding the push rod 20 from getting stuck or being unable to return to its original position.

[0031] like Figure 6 As shown, the push rod 20 is movably connected to one end of the center of the mounting tube 17 with a ball 23. By arranging the ball 23, the friction between the push rod 20 and the swivel 18 can be reduced, and the service life of the push rod 20 and the swivel 18 can be extended.

[0032] like Figure 5 As shown, a screw 26 is fixedly connected to the end face of the mounting cylinder 17, a screw hole 25 is opened on the end face of the rotating shaft 14, the screw 26 is adapted to the screw hole 25, and a bolt 27 is threadedly connected to the side wall of the rotating shaft 14, and the bolt 27 is against the screw 26.

[0033] Among them, when it is necessary to replace the mounting cylinder 17 of a different diameter, it can be rotated and removed, and replaced with a mounting cylinder 17 of other models or sizes, and used in conjunction with the bolts 27, which can further improve stability and avoid loosening or detachment during the drilling process.

[0034] like Figure 2 As shown, the pushing assembly includes a mounting block 10 fixedly connected to the top surface of the support plate 7, a second cylinder 11 is fixedly connected to the side wall of the mounting block 10, the output shaft of the second cylinder 11 passes through the mounting block 10 and is fixedly connected to the transmission box 8, and two limit rods 12 are fixedly connected to the side wall of the transmission box 8, the limit rods 12 pass through the mounting block 10 and are movably connected to it.

[0035] Among them, the stroke of the second cylinder 11 can be adjusted according to the drilling depth. There are many adjustment methods, which belong to existing mature technologies. Therefore, they are not described in detail in this solution.

[0036] Working principle: When drilling wood, first install the drill bit in the designated installation tube 17 according to the drilling requirements. First, insert the drill bit into the designated installation tube 17, then rotate the swivel 18 to move it. The inclined surface of the swivel 18 squeezes the push rod 20 to move toward the center of the installation tube 17. At the same time, the spring 22 is compressed, so that the push rod 20 is inserted into the hole on the drill bit, achieving the purpose of convenient and stable installation.

[0037] After that, the wooden board is placed on the placement board 4, and the first cylinder 6 is started to drive the pressure plate 5 to move downward to press the wood. Then, the motor 9 and the second cylinder 11 are started at the same time. The output end of the motor 9 drives one of the rotating shafts 14 to rotate, and the rotating shaft 14 drives the groove wheel 15 to rotate. The groove wheel 15 makes the installation cylinder 17 rotate synchronously through the belt 16, and the installation cylinder 17 drives the drill bit to rotate. At this time, the output end of the second cylinder 11 drives the transmission box 8 to move, and the transmission box 8 drives the drill bit to drill the wood, so as to achieve the purpose of synchronously drilling multiple holes.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
